Merocyanine and Spiropyran Adsorption on Graphene. [PDF]

ACS Omega
We have investigated the adsorption of spiropyran-based molecular switches on a graphene substrate using a combination of quantum-chemical and force-field-based calculations. Four different spiropyran molecules and their merocyanine isomers have been studied regarding the influence of different end groups on the surface adsorption and intermolecular ...

Noncommutative Switching of Double Spiropyrans [PDF]

The Journal of Physical Chemistry A, 2020
The spiropyran family of photochromes are key components in molecular-based responsive materials and devices, e.g., as multiphotochromes, covalently coupled dyads, triads, etc. This attention is in no small part due to the change in properties that accompany the switch between spiropyran and merocyanine forms.
